Pricing Calculations for HP12C
The HP12C Solutions Handbook provided the Pricing Calculations that provided
the keystroke sequences readily make on various problems. I remaked the sequences so that it is easier to read the instructions. Key Sequences based on various type of problem. (Cost, Price) → Markup ►Cost [ENTER] Price [△%] (Cost, Price) → Margin ►Price [ENTER] Cost [△%] [CHS] (Cost, Markup) → Price ►Cost [ENTER] Markup [%] [+] (Cost, Margin) → Price ►Cost [ENTER] 1 [ENTER] Margin [%] [] [÷] (Price, Markup) → Cost ►Price [ENTER] 1 [ENTER] Markup [%] [+] [÷] (Price, Margin) → Cost ►Price [ENTER] Margin [%] [] Example: FIX 2 Price is 100 and Margin is 45% What is the Cost and Markup? 100 [ENTER] 45 [%] [] display 55.00 // Answer Cost 55 [ENTER] 100 [△%] display 81.82 // Answer Markup Gamo

RE: Pricing Calculations for HP12C
ํalbertofenini thanks for the interest on this Pricing Calculations Key Sequences
Yes this will work on any RPN calculator that have [%] and [△%] functions. Especially work for HP70, 80, 22 and all of the Financial Calculator including the Scientific Calculator as well. These steps is in best use when print it out and cut to small size paper or tape to back of the calculator ready at anytime. I have uploaded the video clip demostraded on how to use it but this one is for Casio calculator. Similar approach work with RPN calculator.

Nice, thank you Gamo,
I have adapted the steps to my HP 48sx: (Cost, Price) → Markup ►Cost [ENTER] Price [%CH] (Cost, Price) → Margin ►Price [ENTER] Cost [%CH] [CHS] (Cost, Markup) → Price ►Cost [ENTER] [ENTER] Markup [%] [+] (Cost, Margin) → Price ►Cost [ENTER] 1 [ENTER] [ENTER] Margin [%] [] [÷] (Price, Markup) → Cost ►Price [ENTER] 1 [ENTER] [ENTER] Markup [%] [+] [÷] (Price, Margin) → Cost ►Price [ENTER] [ENTER] Margin [%] [] Example: FIX 2 Price is 100 and Margin is 45% What is the Cost and Markup? 100 [ENTER] [ENTER] 45 [%] [] display 55.00 // Answer Cost 55 [ENTER] 100 [%CH] display 81.82 // Answer Markup translated with Google 8years elementary school and 2y business school, no bachelor or master; but always interested in simple mathematics and calculators

Quick and easy solutions, I like it, Gamo!
I like how the percent key works in the RPN calculators.

RE: Pricing Calculations for HP12C
For calculator like Casio that calculate Percent this way.
Example: To add 7% to 100 100 [x] 7 [%] display 7 [+] display 107 And calculator that have Constant Funtion that display [k] when press arithmetic twice. These keys steps also find various Pricing Calculations problem. (Cost, Price) → Markup ►Cost [] [] Price [%] (Cost, Price) → Margin ►Cost [] Price [%] (Cost, Markup) → Price ►Cost [x] Markup [%] [+] (Cost, Margin) → Price ► Cost [+] Margin [%] (Price, Markup) → Cost ► Price [+] Markup [+/] [%] (Price, Margin) → Cost ► Price [x] Margin [%] [] Also this can solve for the "Tax Exclusive" or Price without Tax Example: Tax is 7% Price include tax is 100 What is price without tax? 100 [+] 7 [+/] [%] display answer 93.46 [] display tax amount 6.54 To check answer simply add them up 93.46 + 6.54 = 100 Remark: Above calculations using the Casio MS20UC Gamo
